(Note: This concept is obsolete, not necessarily because of Azir, who happens to be a bird-themed Shuriman mage, but mainly because Akrai himself just isn't all that good. Aside from one potentially interesting ability (Astral Form, which I think could work on another kit), his entire kit is fairly bland and doesn't bring enough to the table to justify an brand new champion. Champion and mechanical design have both evolved a lot since I made this post, and I don't think there's really that strong a niche for Akrai beyond "AoE DoT executioner juggernaut", which Darius does significantly better)

Akrai, the Tyrant of the Sands is a concept for a Sands champion with a playstyle closer to that of a mage: his powerful AoE damage, spells and sustain allow him to walk up to crowds and inflict pain upon multiple enemies at a time. As the fight goes on, he becomes stronger, thanks to his low cooldowns and a strong damage ramp-up.

Abilities

Divine Wrath

Akrai'sbasic attack and ability damage is increased by 4% for 5 seconds every time he deals damage.

Divine Wrath stacks up to 5 times, but Akrai cannot obtain more than one stack every 0.5 seconds.

Quell

RANGE:400 / 80º

COST: 50 Mana

COOLDOWN: 5.5 / 5 / 4.5 / 4 / 3.5

Active:Akrai sweeps the area in front of him in an arc with his scepter, dealing 100% AD physical damage to all enemies hit, plus bonus magic damage.

At the end of Astral Form's duration or after taking any action other than moving, Akraiblinks to his Astral Form's location and regains control. Activating Astral Form again instead restores control to Akrai's body without displacing him.

COST: 40 Mana

COOLDOWN: 10 / 9 / 8 / 7 / 6

Active: Akrai flares out and, after a 0.5-second delay, releases a burst of light, dealing magic damage to nearby enemies.
